We supply, install and maintain variable refrigerant flow systems across the Kingdom as an authorised Toshiba and Midea distributor.
A VRF system varies the refrigerant it sends to each indoor unit, so a meeting room full of people and an empty corridor are treated differently by the same outdoor unit. That is why it suits buildings where the load moves around during the day.
It is not a smaller chiller. It is a different answer to a different load profile, and choosing between the two is a question about how the building is occupied rather than how large it is.
Your tenants arrive at different times and occupy different areas. VRF follows that pattern, instead of running a central plant for whoever is in first.
We give you individual room control with heat recovery between spaces that need cooling and spaces that do not, and you do not have to find a plant room for it.
We commission and hand over floors as they complete, so nobody waits for a central plant to be ready before they can move in.
Continuous heavy duty loads, hospitals, data halls and large industrial plant are usually better served by chilled water, and we will tell you so when that is the case.
We profile the load per zone and specify heat pump or heat recovery, the pipe runs, the refrigerant volume limits and the ventilation strategy that has to sit alongside it.
We braze and pressure test the pipework, keep vacuum and charge records, configure the controls per zone, and hand over a commissioning record with the system.
We service the filters and coils, check the refrigerant and verify the controls and sensors on a schedule, so you keep performance rather than having to recover it.
Toshiba VRF air conditioning at the Abdul Latif Jameel building, supplied and installed by Green Flash as an authorised Toshiba distributor.
More of our work is on the projects page.
It depends on the load profile, not the tonnage. Long hours at part load with varied occupancy favour VRF. Continuous heavy load favours chilled water.
We supply Toshiba and Midea as an authorised distributor in Saudi Arabia, and we supply LG where the project specifies it.
Yes, when the units are selected against local design conditions rather than catalogue ratings, and the condensers have the airflow and the servicing access they need.
Yes, after a survey that records the condition of the pipework, the charge and the controls.
Tell us the floors, the uses and the occupancy pattern. We will tell you whether VRF is the right answer and what it costs to run.
